2002 Chevy venture theft deterrent module

I lost my key for my 02 Chevy venture the key was too expensive so I just took the steering column out of another venture at the junk yard and used that cylinder and key. We programmed the new key to the theft deterrent module and it worked. But only for about a month than one day the battery died and the module forgot the key. Now it will not relearn the key!!! Ugh!!! I called the dealership and they said I would need a new tdm can I get that at pull apart?

UGH!!! OK I got the new theft deterrent
module and the key still would not
program to the vehicle. In fact now my
odometer is going haywire and so is my
radio(FLICKERING AND SUCH) we've
come to the conclusion that it is most
definitely the bcm, whereas I think it may
have been flooded during a recent storm,
which marked the begining of this issue. If
I get a new bcm from the junk yard do I
need to flash or program it in order to
utilize it or will it automatically work. If I
have to program it is there a cheap way to
do so?

Of course losing the key initially was it but
I hit a big puddle two days before the van
forgot the new key and it shut down
moments later and the same flickering
happened right before it shut down.
However it charged back up that day

Also before I had lost the key a similar
situation had happened beforehand
flickering and such during a rain storm and
a sudden shut down of vehicle after hitting
a large puddle, the wireharness on the
passenger side was all severed and
corroded , we fixed that, and everything
was okay, until the next time i hit a large
puddle than the same thing happened.
